Bluetooth Helmet Headsets?

I know it's not on your list Ted but I've been pretty happy with my 1st generation Chatterbox XBi. I only use it to hear directions from my GPS and I did use it once to place a phone call while I was getting gas.

I bought the Scala Rider Q2 team set about a year ago. I ride with the wife 2 up and we used them a lot over the 12,000 miles we put on in the last year. We turn them on in the morning and recharge at night on trips and they have never let us down even after being on for 12 hours. I liked them so much I bought the new G4 team set about three weeks ago. Those are even better. We can now listen to the iPod bluetooth instead of using the wires. The reception is better and the speakers are louder. I bought my G4 Teamset from Baird Cycle out of Elkhart, Indiana for $310. He has the Q2 Team Set for a little over $200. He has a ebay store under the name of sport bike needs. No matter where you get them you will not regret the purchase.

Sena SMH10

Just used these units on a trip to the Blue Ridge Parkway. Very user friendly, excellent audio and modest range.

They seem to be good for about a half mile or so which is good. Bike to bike com is only two parties at a time though, they are a blue tooth connection protocal and not like walkie talkie radios where several can be on the same frequency at once.

Battery is non replaceable but should it ever not take a charge I am sure a workaround will be available or the technology will have already been superceded by then. Hell of a lot of fun choosing music, talking with other riders and making the occasional phone call. Worked with my Garmin by cable too (Nuvie 760.)

+1 on Sena

Ted - I use my Sena for;

iPod music and (mostly) podcasts
Bike to Bike and rider to passenger communication
Receiving phone calls
XM radio

I use the system while wearing foam earplugs - these eliminate the wind noise, but the fidelity and volume on the Sena come through. The Sena is smart, interrupting entertainment to take a call or communication from another rider - and then automatically going back after the call. If the source was an iPod (or MP3 Blackberry source which works very well) it pauses the soundtrack and returns where it left off. I've used it with modular and full face helmets - installation is easy, 5 minutes tops.

Battery life is a full day - I've run 14 hours with no problem.

The system isn't fussy, easy to use with gloves, and never had any problems with rain.

Factory support is top notch - I bought mine thru Adam at Rocketmoto.com - very knowledgable reseller with very good prices. Usual disclaimers.
